Abstract:
BACKGROUND/AIMS: Endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) has been used as a treatment for early gastric cancer (EGC). This study was performed to evaluate the usefulness of the endoscopic findings for diagnosing the depth of invasion in EGC patients. METHODS: We retrospectively analyzed the endoscopic findings of 558 EGC patients who were diagnosed after gastrectomy, EMR or ESD at Dong-A University Hospital between 2000 and 2006, and we divided them into two groups (the mucosa group versus the submucosa group). Nine factors were assessed (Type I or IIa: surface color, surface irregularity, the Yamada type and pitting on the apex; Type IIb: surface color, surface irregularity and marginal definiteness: Type IIc or III: ulcer base irregularity, shape of the converging folds, center of the converging folds and marginal elevation). The tumor size and histologic type were assessed for all the EGCs. RESULTS: Ulcer base irregularity (p=0.005), marginal elevation (p=0.001), and the shape of the converging folds (p=0.018) showed significant correlation with the depth of invasion in type IIc or III EGCs. Tumor size ( <2 cm) showed a significant correlation with mucosal invasion for all the EGCs. CONCLUSIONS: These results support the usefulness of the endoscopic findings for making the therapeutic decision for performing EMR or ESD through predicting the depth of invasion of EGCs.
